- Bring down the splash screen when a vty is opened for the first
  time.
- Make sure the splash screen/screen saver is stopped before
  switching vtys.
- Read and save initial values in the BIOS data area early.
  VESA BIOS may change BIOS data values when switching modes.
- Fix missing '&' operator.
- Move ISA specific part of driver initialization to syscons_isa.c.
